Journal ArticleDOI
Orbital angular momentum: origins, behavior and applications
Alison M. Yao,Miles J. Padgett +1 more
TL;DR: In this paper, it was shown that if every polarization vector rotates, the light has spin; if the phase structure rotates and if a light has orbital angular momentum (OAM), the light can be many times greater than the spin.
Journal ArticleDOI
Free-space information transfer using light beams carrying orbital angular momentum
Graham M. Gibson,Johannes Courtial,Miles J. Padgett,Mikhail V. Vasnetsov,V. A. Pas’ko,Stephen M. Barnett,Sonja Franke-Arnold +6 more
TL;DR: The transfer of information encoded as orbital angular momentum states of a light beam is demonstrated, which is resistant to eavesdropping and gives an experimental insight into the effects of aperturing and misalignment of the beam on the OAM measurement and demonstrates the uncertainty relationship for OAM.
Journal ArticleDOI
Tweezers with a twist
Miles J. Padgett,Richard Bowman +1 more
TL;DR: The fact that light carries both linear and angular momentum is well-known to physicists as discussed by the authors, and one application of the linear momentum of light is for optical tweezers, in which the refraction of a laser beam through a particle provides a reaction force that draws the particle towards the centre of the beam.
Journal ArticleDOI
Mechanical equivalence of spin and orbital angular momentum of light: an optical spanner.
TL;DR: It is shown that the spin angular momentum of +/-?per photon associated with circularly polarized light can add to, or subtract from, the orbital angular momentum to give a total angular momentum.
Journal ArticleDOI
Measuring the orbital angular momentum of a single photon.
TL;DR: This work demonstrates its viability by sorting four different orbital angular momentum states, and is thus able to encode two bits of information on a single photon, having implications for entanglement experiments, quantum cryptography and high density information transfer.
